Having established a base on the Syrian coast, Vladimir Putin last week began air strikes on ISIS and other rebel forces seeking to overthrow Bashar Assad.

A longtime ally of Syria, Russia wants to preserve its toehold on the Mediterranean, help Assad repel the threat, and keep the Islamic terrorists out of Damascus.

Russia is also fearful that the fall of Assad would free up the Chechen terrorists in Syria to return to Russia.

In intervening to save Assad, Putin is doing exactly what we are doing to save our imperiled allies in Baghdad and Kabul.

Yet Putin’s intervention has ignited an almost berserk reaction.

John McCain has called for sending the Free Syrian Army surface-to-air missiles to bring down Russian planes. Not only could this lead to a U.S.-Russia clash, but U.S.-backed Syrian rebels have a record of transferring weapons to the al-Qaida affiliate.

The end result of McCain’s initiative, sending Stingers to Syria, could be airliners blown out of the sky across the Middle East.

Hillary Clinton wants the U.S. to create a no-fly zone. And Friday’s Wall Street Journal endorsed the idea:

“Mr. Obama could make Mr. Putin pay a price. … In Syria the U.S. could set up a no-fly zone to create a safe haven for refugees against … Mr. Assad’s barrel bombs. He could say U.S. planes will fly wherever they want, and if one is attacked the U.S. will respond in kind.”
